I have no business posting in this threat but ...my Golden Retriever is just getting over being sick the past few days (24 hours of unexplenation) which caused her to vomit twice ...and from our visit to the vet to investigate ...alot of other dogs have fallen ill too..i wasnt at the G2G so im thinking theres probably more to the story then something they ate....make sure your dogs shots are all up to date especially when they are going to be playing in groups
